最近,对记忆形成中新神经元的研究集中在一个特定的功能——模式分离上。然而,很难将行为任务中测试的分离形式与根据计算和电生理学角度概念化的分离形式相协调。在这里,我们提出了一种记忆分辨率假说,该假说考虑了广泛调谐的年轻神经元和高度特异性的成熟神经元的独特信息贡献,并描述了记忆的保真度如何与空间和情境辨别相关。
Recently, investigation of new neurons in memory formation has focused on a specific function – pattern separation. However, it has been difficult to reconcile the form of separation tested in behavioral tasks with how it is conceptualized according to computational and electrophysiology perspectives. Here, we propose a memory resolution hypothesis that considers the unique information contributions of broadly tuned young neurons and highly specific mature neurons and describe how the fidelity of memories can relate to spatial and contextual discrimination.
